I installed the official stunnel 4.33 binary on Windows XP/32.
And, when I execute "stunnel -version", a popup window appears with
the following message:
---------------------------
stunnel 4.33 on Win32 (not configured)
---------------------------
Stunnel server is down due to an error.
You need to exit and correct the problem.
Click OK to see the error log window.
---------------------------
OK
---------------------------
Shouldn't that just work? What may be the cause for the problem?
Indeed, I didn't configure stunnel yet. But I also realized that when
I change something - for example the log level - in "stunnel.conf",
then this is ignored by "stunnel -version".
After clicking "OK" to close the popup message, I get some more info,
though meaningless to me:
